That is true and very tempting but the stability issue is my biggest concern. I question how much time was put into developing the drivers for Tri-Fire over Quad-Fire. Also, maybe this is a silly statement, but whats the REAL difference between 3 GPU's and 4? I mean, I'm all about all power and the word overkill should be my moto but what benifits do i experience with 4 instead of 3?

3 is enough man, you'd need to upgrade your psu aswell if you went 6990x2, trifire you can run straight off the bat. Also if your not doing 3x 2560x1440 or higher, trifire is the better solution for you.

Would it make a difference if i said i had a Corsair 1000w from my current system that could be put to use along side the AX1200?

Sorry, not to interrupt anything.

A single +12v rail AX1200 for daily 24/7 gaming is good enough for Quad setup + pumps + fans etc.

When going for OC stability, I personally add another 1,250w dedicated to 4 GPUs, to minimize +12v drops run off a single PSU. A single 6990, on AUSUM BIOS TDP is 450w without overclock.

No need for 2 PSU.

With a single Corsair AX1200 I was driving Quad 6990+6970+6970 all OC with 1.25v, i7 2600K at 5.3 24/7, 32 (yes... 32) Gentle Typhoon fans, 16Gb of RAM, 4 pumps MCP655, Blu-ray writer, 4 fan controllers...

And everything was rock-stable.
